Compound atmospheric drivers of the 2025 Los Angeles urban firestorm…Analysis shows driven by rare “jet-forced Santa Ana” wind wextreme northerly flow, subsidence & mountain waves. While extreme sfc winds not unprecedented, occurrence before 1st rains was uncommon.

Really did not know that mega-constellations could affect space telescopes!
Ever since the first SpaceX Starlink satellites were launched in 2019, astronomers have warned that satellite constellations will contaminate images of the night sky.
A new study finds that in the next 2 decades, even space-based telescopes could face the same issue. https://scim.ag/3XyjcIw

Satellite fleets pose problems for space telescopes, too
Proposed “megaconstellations” would contaminate images from telescopes in low-Earth orbit, including Hubble

💯...but alongside 'reducing uncertainty', provide their best estimate of it. Those scores always seemed so weird without some kind of uncertainty range.
This is the correct take on the whole Zillow fiasco

The new Global Fire Emissions Database (GFED5, 2002–2022) shows that at the global scale 1) by far, most area burned are grasslands; 2) area burned is declining; & 3) fuel consumption is increasing: ie, fires are increasing in forests & encroached grasslands.

In the century leading up to 1975, nearly 6000 freighters went down in the Great Lakes.
The Edmund Fitzgerald was the last.
The last. In 50 years, not a single commercial freighter has been lost in the Great Lakes.
Why?
It's NOAA. Of course it's NOAA.

Some US members of congress wrote the Canadian ambassador on July 7, 2025 with respect to fire management and the resulting smoke from Canadian forest fires. The reality is that the increase in fires & smoke is largely due to human-caused climate change, and we will see more fire in the future.
